Bently Nevada 31000-16-05-00-036-03-00 English Proximity Probe Housing Assemblies

Description

The 31000-16-05-00-036-03-00 is an English proximity probe housing assembly designed to provide robust mechanical and environmental protection for 3300 XL eddy-current displacement sensors. This configuration features a 3300 XL 8 mm proximity probe (Option 16) with a 0.5 m probe cable length (Option 05) and is configured without a standoff adapter (Option 00). The assembly is engineered to facilitate external access to the proximity probe and its extension cable, allowing for critical gap adjustments or probe replacements without requiring machine disassembly. Constructed from high-strength polyphenylene sulfide (PPS) and corrosion-resistant stainless steel, this housing is fully compliant with API 670 standards for externally mounted proximity probe housings. It is suitable for use in radial vibration and axial position measurement applications where environmental sealing is required. This specific unit (Option 03) includes two plugs and one M20 fitting with a cable seal grip, providing secure routing for armored probe cabling. The assembly is intended for use in industrial environments requiring protection against process fluids, moisture, and mechanical abrasion.

Features

• Equipped with a 3300 XL 8 mm proximity probe for high-accuracy vibration and position measurements.
• Option 05 designates a 0.5 meter (20 in) integral probe cable.
• Option 03 fittings include two plugs and one M20 cable seal grip, specifically compatible with armored probe cabling.
• Manufactured from polyphenylene sulfide (PPS) for superior chemical resistance and structural integrity.
• Designed for compliance with API 670 standards for externally mounted sensor protection.
• Allows for probe gap adjustment without disrupting the machine casing.

Applications

• Radially mounted transducers for shaft vibration monitoring.
• Keyphasor measurements in rotating machinery.
• Industrial environments requiring external access for maintenance and calibration.
• Protection of eddy-current probes in machinery cases exposed to process fluids or harsh ambient conditions.

Installation Guidelines

• Ensure the housing cover is tightened securely after probe gap adjustment to maintain the environmental seal.
• When using the M20 cable seal grip (Option 03), ensure the cable grommet is properly seated to prevent moisture ingress.
• If the machine casing is thin or non-metallic, ensure the housing is properly grounded to the machine frame to maintain signal integrity.
• Hole plugs provided (Option 03) must be tightened to 0.5 N-m (5 in-lbs) to ensure proper sealing of unused ports.
